New York Sen. Charles Schumer blasted New Jersey Gov. Chris Christie’s proposal to spend $1.8 billion of Port Authority of New York and New Jersey money on roads and bridges west of the Hudson.

The Republican governor wants to use money that the bi-state agency had committed to a cross-Hudson rail tunnel to repair crumbling northern New Jersey roads like the Pulaski Skyway. Christie canceled the tunnel project, known as Access to the Region’s Core, last year.

“Asking the Port Authority to take capital funds and redirect them on this scale, a scale never before contemplated, would be a mistake that rivals, and perhaps even surpasses, the cancellation of (the rail tunnel) as a risk to our region’s future,” Schumer said. “It could well begin the cannibalization of Port Authority dollars.”

Schumer, a Democrat, also called Christie’s decision to cancel that tunnel “one of the most shortsighted in New York’s history.” Schumer’s attack on Christie’s transportation priorities and call to “get this project going again” come more than two months after the governor’s final decision to end work on the cross-Hudson tunnel.

His statements on the Port Authority money Tuesday also mark the first pushback from New York against a plan proposed by Christie to fill a giant gap in the fund used to pay for New Jersey transportation projects. Christie and New York Gov. Andrew Cuomo must agree on where Port Authority money is spent. Cuomo has so far been silent on Christie’s plan.
